Specification of Letters Patent.

Patented Feb. 29, 1916.

To all whom it may concern Be it known that I, SIMON GOTTLIEB, a subjectof the Emperor of Austria-Hungary, and a resident of the city of NewYork borough of Manhattan, in the county and State of New York, haveinvented a new and Improved Machine for Cleaning Ceillngs, of Which thefollowing is a full, clear, and exact description.

This invention relates to brushing and scrubbing, and has particularreference to means for cleaning ceilings or other overhead structures.

Among the objects of the invention is to provide a machine of a portablenature adapted to be moved about on a floor or other analogous support,such machine hav ing facilities for brushing a ceillng or sweeping dust,dirt, cobwebs or the like from the same by means operable by theoperator standing on the floor.

A further object of the invention is to provide means for washing orscrubbing a ceiling while at the same time washing. fluid may bedelivered against the ceiling, means being provided to collect thewashing fluid as it falls or is wiped from the ceiling.

With the foregoing and other objects in view, the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed herein, still for the purposeof illustrating apractical embodiment thereof reference is had to the accompanyingdrawings, in which like reference characters designate the same parts inthe several views, and in which- Figure l is a vertical transversesection on the line 11 of Fig. 2; Fig. 2 is a side elevation of thesame, looking toward the left in Fig. 1; Fig. 3 is a plan view; Fig. 4is a horizontal section on the line H of Fig. 1; Fig. 5 is a verticalsectional detail on the line 55 of Fig. 1; and Fig. 6 is a detail of amodified form of cleansing tool adapted for use with this machine.

Referring now more particularly to the drawings, I show a receptacle 10movably supported upon a vehicle 11 having wheels 12 and 13 and. alsohaving a tongue 14 representing means,for guiding or manipulating thevehicle along the floor.

The receptacle is provided with a rigid top 15 constituting supportingmeans for the various operating parts.

vided with a filling opening 16 through WhlCll cleansing fluid 17 may besupplied to one compartment 18 of the receptacle. Adacent thecompartment is another compartment 19 adapted to receive the dirtywater. Either compartment may be drained at the bottom by means of asuitable spigot 20.

At 21 I show a crane comprising a pluralty of adjustably connectedjointsor parts including a tubular post 22, and a stem 23 secured in positionin the post by means of a set screw 24, said crane also including links25 and 26 connected by an adjustable link 27 composed of two parts,connected by means of a bolt and wing nut 28 through slots 28. At theupper end of the crane is supported a holder 29 adapted to hold orsecure in position for operation a sponge 30 or a brush 30, dependingupon the character of the cleansing to be performed. The post is rigidlysecured to and extends upwardly from a slide 31 guided for horizontalreciprocation in a guideway 32 upon the receptacle top 15. The slideincludes a rack 33 projecting downwardly through a slot in the cover 15and meshing with a gear 34 mounted' upon a rock shaft 35 journaled inthe receptacle and having on its outer end a pinion 36 with which anarc-shaped rack 37 meshes. The latter rack is journaled upon a stud 38on the outside of the receptacle and is adapted to be oscillated througha lever 39 by an operator standing upon the floor. This operation of thelever causes the slide 31 and parts supported thereon to be reciprocatedalong the receptacle top and thereby the sponge or other cleansingmedium would be caused to sweep or scrape to and fro along the ceiling.The adjustability of the parts at 22 and 23 is primarily for the purposeof providing for the operation of the cleansing tool bringing it intocontact with the ceiling. The adjustment at 28 in the double link 27 isfor the purpose of tilting the upper part of the link 27 and partssecured Said top is pm- I thereon to one side of the vertical plane ofthe cleansingoperation. For this purpose I show an air pump 39communicating with' the upper portion of thecompartment and throughwhich the space above the fluid therein may be highly chargedWith-compressed air.

At 40 is indicated a pipeleading from a point near the bottom of thecompartment 18 upwardly through a flexible tube 41 to a rose 42supported approximately in the vertical center of the receptacle. Thedelivery of the fluid through the tubes 40 and 41 may be controlled by avalve 43. The rose is supported in operative position by means of ajointed arm 44 supported upon the top of the receptacle. With thecompartment 18 charged with compressed air and the rose so positioned asto direct the flow up- Wardly, the operator will open the valve 43,permitting the air pressure within the compartment to force the fluidupwardly' through the tubes 40 and 41 and through the "rose in as greata volume as required. This action may take place independently or at thesame time that the tool holder 29 is reciprocated to and fro along theceiling.

The dirty water dropping 'or being scraped from the ceiling may bedisposed of by collecting it in a pan 45 located below the rose andfield of operation of the cleansing tool. Said pan has a downwardlysloping bottom with which'a pipe 46 communicates preferably at itscenter, said pipe leading into the compartment 19 through the top 15.The pipe 46 may be telescopic for the purpose of extension of the pipeor for the purpose of removing the pan from the receptacle whenrequired.

I claim:

1. The herein described machine for cleaning ceilings comprising areceptacle, means to support the receptacle movably upon a floor, saidreceptacle being adapted V to contain a cleansing fluid, means todeliver the fluid in regulatable quantities upwardly I against theceiling above the receptacle, and

the top of the first mentioned support tov support the crane and causethe movements of the cleansing tool.

3. In a machine for cleaning ceilings, the combination of a :mainsupport, portable supporting means for the main support, a slide guidedfor reciprocations in a horizontal plane at the top of the main support,a vertically adjustable crane carried by and extending upwardly from theslide, a cleansing device carried by the upper end of the crane, andmeans mounted upon the main support to cause the reciprocations of theslide and parts supported thereon.

4. In amachine for cleaning ceilings, the combination of a main supporthaving a guideway in its top, a slide mounted in said guideway andmovable to and fro in a horizontal plane, said slide having a rackprojecting downwardly therefrom, a vertically adjustable crane extendingupwardly from the slide, a cleansing tool carried by the crane, and rackand pinion devices journaled on the main support and cooperating withthe aforesaid rack to cause the reciprocations of the slide.
